Realistically, if Trump’s margin in PA were over 50K then the Philly vote fraud machine couldn’t manufacture enough votes — not that they won’t try. But the secondary reason for the long count is to force Trump to go to the federal courts to stop the counting. The Left will point to that and — like Bush V Gore — they will say that Trump was “selected not elected”. It will all come down to denying Trump the legitimacy that he needs to govern in his 2nd term.
They won’t be able to deny his legitimacy when he wins with well over 300 electoral votes and even Gallop has said he might well win the popular vote.
